ATI Radeon HD 4850 and 4870 specs leaked?

AMDs next-generation RV770 graphics processor was initially expected to debut around late June, but if recent reports are to be believed, the companys graphics division is running ahead of deadlines and set to launch their Radeon HD 4000-series graphics cards in the next few weeks.

German tech site Hardware-Infos has apparently gotten hold of some leaked specs, launch schedules, and prices for three cards in the upcoming Radeon HD 4000-series GPUs, and has published them online for all to see. Starting at the high-end, the Radeon HD 4870 ($349) will reportedly feature 480 stream processors  rather than the 320 found in the 3850 and 3870  an 850MHz core speed, 1GB of 1935MHz GDDR5 RAM, and a 256-bit memory interface.

The Radeon HD 4850 ($269) will share almost the same specs as its higher-end counterpart, except it comes with 512MB of RAM and has lower core and memory speeds of 650MHz and 1728MHz. Meanwhile, on the lower-end, a GDDR3 version of the 4850 is also claimed to be in the works with a memory clock of 571.5MHz.
